Once I turn my headlights on they are fine till around 15 mins or so. they just flicker on and off a couple of times and they go off completely. I ve already changed the dimmer switch and checks all ovious grounds. and other suggestions? i wanna go toa car show this weekend but without any head lights it might be a problem.

 

You may need a new battery. Take your car to autozone or any other auto part shop and they'll determine if it's good or not.

 

batteries an optima and i tested it and its perfect so im thinking the relays are going bad
